[QUOTE="MuleHunter, post: 670029, member: 14190"] No. These were tested at a muzzle velocity of 2,990fps with the 175gr and at 2,950fps with the 165gr. Brian Litz tests Berger bullets from a 3,000fps muzzle velocity down to 1,500fps and that average BC across those velocity bands are the ones Berger lists on their website for their bullets. My testing gets as close to his results as possible without using sonographs at multiple ranges. In my experience when you approach the 3,150-3,300fps range the average BC gets higher. My goal for testing these bullets was to mimic Litzs' testing as close as possible so that the average shooter shooting them in the 2,800-3,000 fps range would have an accurate average BC to start with. The cartridges used were a 270 WSM and a 270 Win I did a little write up on how I tested the 175gr in the ELR section of this forum. [/QUOTE]
